Screen construction



May 5, 1931. D. E. SHRAUGER SCREEN CONSTRUCTION Filed Feb. 24, 1930 Patented May s, i931 PA'rsni orifice DARIUS E. SHRAUGER, OF ATLANTIC, yIOWA SCREEN CONSTRUCTION Application filed February 24, 1930. Serial No.7430,575.

The object of my invention is to provide a screen construction for windows which is simple, durable and comparatively inexpensive to manufacture.

A further object is to provide a screen construction consisting of supporting bars adapted to be secured to the sides of a frame of aV window and a screen frame adapted to contact with the inner surfaces of the supporting bars whereby the screen frame may be installed in position or removed from the inside of a building.

A further object is to provide supporting bars with inwardly opening channels and a screen frame with flanges litting into the channels to provide a fly tight joint which, however, provides for expansion and contraction of the window frame relative to the screen frame and for variation iii the widths of window frames to which the screen construction is applied.

Still a further object is to provide a screen frame having a section thereof hinged whereby the effective height of the screen frame may be reduced to facilitate mounting and tilting of the screen relative to the window frame.

lVitli these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects con` templated are-attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure l is an outside elevation of a window frame showing my screen construction applied thereto.

Figure 2 is an enlarged sectional view on the line 2-2 of Figure 3. n

Figure 3 is a sectional view on the line 3 3 of Figure l illustrating the screen being installed.

Figure l is an enlarged sectional view on the line 4--1 of Figure l and Figure 5 is an inside elevation of one of the lower corners of the screen construction.

On the accompanying drawings l have used the reference numeral 10 to indicate the sill of a window f ame of the ordinary doublesash type. rlhe side jainbs thereof are indicated at l2. The lower cross bar of the upper sash of the window is indicated at l5.

My screen construction consists of a pair of supporting bars A and a screen frame B. Each supporting bar A has an attaching flange 14 adaptedV to be secured tothe side lambs l2 (such as to the blind stop 16 thereof) by means of screws or the like 18. Each supporting har A further includes a .vertical channel portion 2O terminating at its upper end in a stop flange 2l.

The screen frame B is preferably of sheet metal construction as fully described in my co-pending application, which issued into Patent N o. 1,779,859, under date of Oct. 28, 1930. It includes a screen covering 22 and a movable section 24. The movable section 24 is hinged as indicated at 26 to the screen frame B.

The section 24 of the screen frame B is provided with an upper flange 28 adaptedY to contact with a flange 30 ofthe screen frame B when the screen construction is in installed position as shown in Figure 2. Asill flange 32 is provided on the lower edge of the section 24 and thev section is provided with a pair of handles 34. A latch 36 is provided for each side edge of vthe screen frame B and section 2A; as will hereinafter be fullv set forth. i L

Pfam/ical operation Y In the practical operation of my device, assuming it to be installedas shown in Figure 2, it will be seen rthat the vinner face of the upper end of the screen frame B contacts with the outer face of the cross bar l5 of the upper sash of the window. The sill flange 32 contacts with the sill l0 of the windouw frame. This excludes the entrance of flies at the top and bottom ends vof the screen frame B. Flies areeXcluded at the side edges bv means of anges 38 which lits into the coniparatively wider channels 20.

The effective height of the screenfranie B may be shortened to facilitate removal of the screen frame from the supporting bars A by swinging the hinged sect-ion 24to the dotted line position shown in Figure 2. First of Cal all, however, the screen 'frame B must be raised until the upper end thereof contacts with the stop flanges 2l of the supporting barsA whereupon there will be su'liicient clearance to swing the hinged section Q4 as shown by dotted lines in Figure 3 and indicated by the arrow 40. rl`he ellective height oi the screen frame B is now shortened so that it can'be'lowered to a. position where the upper end thereof is no longer in contact with the cross bar lll. rlie screen 'ramegl may then be swung inwardly as shown in the full line position in Figure 3, the hinge'dseo tion 24 also shortening the lengtlrot' the screen B for the purpose of clearing'the stool 42 of .the window frame. ln replacing the screen trame, the operations above outlined are reversed.

lt will be seen that `provision has vbeen made to use the cross bar l5 as shield against .the entrance otliies and that further means'has been provided to allow the screen iframe to be moved out of Contact with thisV bar so-,that the screen :frame can swing inwardly for removal of .the screen 'from the supporting bars A, vrlhis is desirable as, if the screen height were not shortened, the lower end could-not be pulled inwardly without thescreen pivoting on the rlower outer edge of kthe cross bar lland springing the supporting bars A out of shape.

Although il .have illustrateda screen coveringffor the frameB, glass maybe used stead Y whereby a conrenienlly installe-.ble storm sash is provided. The construction maybe used on full Ywindow trames where other than afdouble sash window is usedas well as .on 4thehalf window illustrated.

Some changes maybe made in the constructionand arrangement .of the parts o1 lllmy device without departing` from vthe real spirit andjpurposerof myinvention, and vit is my intention to cover by my claims, any modified dormsof structure o-r use of mechanical equ'iif'alents which may be reasonably included within their scope.

I claim as my invention: Y

l. In a screen construction for a window having a cross bar,a pairof supporting bars adapted to be securedlto'thesides of the irame of said window, a screen frame adaptedto contact with the inner suracesol said supporting bars and the outer surf ce ot' said cross bar, .and 'thus be'coniined against both outward and inward movement -respectively at-its upper end and means torretain it against the Vsupporting bars at :its lower end, said screen vframe vhaving a section thereof morable with respect tothe remaining portion thereof whereby it may-be shortened to lower it from Contact with said cross bar `whereby itinay thereafter ber-emoved inwardly from contact with said supporting-bars. 4 n

2. ln a screen construction for a double sash window, ascreen frame,-means for supporting the same with its upper end in contact 'ith the outer face of the lower cross rail of the upper sash, said screen frame having a. movable portion which contacts with vthe sill of the frame of said window when in vfrom installed position.

3. In a screen construction for a double sash window, a--screen frame, means for supporting the ,same comprising supporting bars adapted 'to be secured tothe sides of the frame of said window, said screen frame having its upper end'in Contact with the Outer face of the lower cross rail of the upper sash and its louter tace in Contact with the inner faces of said. supporting bars and thereby confined therebetweeinand means for-shortening the ei'iqective height of the screen frame whereby it maybe lowered from contact with said cross bar and thereafter moved inwardly from contact with said supporting bars.

1l. .ln a screen construction for a window having a cross bar, a pair ofsupportingbars adapted to be secured to the sides of the frame or", said window,.a screen 'frame adapted to contact with the innersurfaces of said supporting bars andthe outer surface of said cr-oss bar and'be conined therebetween at its upper end, andinanuallyoperable means to retain the lower end of the screen `frame in contact.v with .the supportingibars said screen rame being conlinedbetween saidmanually operable means and vthe supporting .bai-s".
